This etch contains both 3'6" and 4'0" wide brackets, and the associated trimmers and landing. To model a 3-doll cantilever or equal tee signal, you will need two 4'0" brackets. Also included on the fret are rocking shaft brackets and levers, and an "Engines must not enter this shed" sign.

The actual size of the fret is 73 x 95mm; it is etched in 0.016" brass.

To model a complete signal, you will need:

Base post (S028)
Dolls (S033)
Signal arms (S03 GC lower quadrant or S012/1 LNER/BR upper quadrant)
Finials (not yet in the MSE range)
Lamps (SC023 lower quadrant or SC025 upper quadrant)
Balance levers and weights (SC041 lower quadrant, included on S012/1 for upper quadrant)
Ladder (S7/09, S09/3, S09/4 or S09/5).
